exhibit reliable lineaing superelasticity and stable elastic modulus, with strain as high as 4%. The residual strain (εr) increases with increasing porosity whereas decreases with increasing number of compression cycles. The correlation between εr and other influential factors largely follows a hyperbolic trend. Key words: porous NiTi alloys; superelasticity; residual strain; elastic modulus ......

was processed by plasma electrolyte oxidation. The microstructure, crystal structure bonding strength and elastic modulus of the film were discussed. The results show that a porous titania is formed on Ti substrate and its bonding strength with the substrate is higher than 30MPa. The elastic modulus increases with the increase of applied voltage due to the change of crystal structure of titania......
